The worldwide incidence of preterm birth: a systematic review of maternal mortality and morbidity

TLDR
Developing countries, especially those in Africa and southern Asia, incur the highest burden in terms of absolute numbers, although a high rate is also observed in North America.
Abstract
Resumen Incidencia mundial de parto prematuro: revision sistematica de la morbilidad y mortalidad maternas Objetivo Analizar las tasas de prematuridad a nivel mundial para evaluar la incidencia de este problema de salud publica, determinar la distribucion regional de los partos prematuros y profundizar en el conocimiento de las actuales estrategias de evaluacion.Metodos Los datos utilizados sobre las tasas de prematuridad a nivel mundial se extrajeron a lo largo de una revision sistematica anterior de datos publicados e ineditos sobre la mortalidad y morbilidad maternas notificados entre 1997 y 2002. Esos datos se complementaron mediante una busqueda que abarco el periodo 2003–2007. Las tasas de prematuridad de los paises sin datos se estimaron mediante modelos de regresion multiple especificos para cada region.Resultados Estimamos que en 2005 se registraron 12,9 millones de partos prematuros, lo que representa el 9,6% de todos los nacimientos a nivel mundial. Aproximadamente 11 millones (85%) de ellos se concentraron en Africa y Asia, mientras que en Europa y America del Norte (excluido Mexico) se registraron 0,5 millones en cada caso, y en America Latina y el Caribe, 0,9 millones. Las tasas mas elevadas de prematuridad se dieron en Africa y America del Norte (11,9% y 10,6% de todos los nacimientos, respectivamente), y las mas bajas en Europa (6,2%).Conclusion El parto prematuro es un problema de salud perinatal importante en todo el mundo. Los paises en desarrollo, especialmente de Africa y Asia meridional, son los que sufren la carga mas alta en terminos absolutos, pero en America del Norte tambien se observa una tasa elevada. Es necesario comprender mejor las causas de la prematuridad y obtener estimaciones mas precisas de la incidencia de ese problema en cada pais si se desea mejorar el acceso a una atencion obstetrica y neonatal eficaz.

Progestogens for the prevention of preterm birth and risk of developing gestational diabetes mellitus: a meta-analysis

TL;DR: The results of the present meta-analysis clearly indicate that women which receive supplemental 17OHPC for the prevention of PTB have increased risk of developing GDM.

Executive functioning deficits in young adult survivors of bronchopulmonary dysplasia.

TL;DR: This study represents the largest sample of survivors into adulthood of BPD and is the first to show that deficits in executive functioning persist, and children with BPD should be assessed to identify cognitive impairments and allow early intervention aimed at ameliorating their effects.

To do or not to do emergency cervical cerclage (a rescue stitch) at 24-28 weeks gestation in addition to progesterone for patients coming early in labor? A prospective randomized trial for efficacy and safety.

TL;DR: ECC is effective in pregnancy prolongation when judiciously used in combination with progesterone compared to progester one alone, and neonatal outcomes in terms of early neonatal deaths were lower in this group.

Evaluation of Novel Biomarkers for Early Diagnosis of Acute Kidney Injury in Asphyxiated Full-Term Newborns: A Case-Control Study.

TL;DR: Serum Cys-C, β2-MG, urine NGAL, and α1-MG are early specific indicators for the diagnosis of renal injury after neonatal asphyxia and combined detection of these parameters could aid clinical evaluation of renal injuries in asphyxiated neonates.

The preterm parturition syndrome

TL;DR: The evidence indicating that the pathological processes implicated in the preterm parturition syndrome include: intrauterine infection/inflammation; uterine ischaemia; (3) uterine overdistension; (4) abnormal allograft reaction; (5) allergy; (6) cervical insufficiency; and (7) hormonal disorders (progesterone related and corticotrophin‐releasing factor related).

Epidemiology of preterm birth

TL;DR: Over the past 20-30 years advances in perinatal care have improved outcomes for infants born after short gestations, but there is still uncertainty and incomplete recording of estimates of gestation in developed countries.
